Bob,
Did you blow the image up? (thanks to Alan for having all of this info handy) I could be wrong, but the tube in question still looks to be far too thick to be blackened stainless - and there is no sign of metal at all - it looks black all the way in. Plus there is no sign of the markings of a hammered-in fitting which would cause metal damage. I think its thickness and color is consistent with SiC and the stainless capsule has been removed. The lack of an end cap (or evidence that one was ever there) also makes me think that this tube is not steel. From: Bob Higgins Jones, I believe you are mistaken. The bottom picture shows the thick alumina (probably not high purity, but rather an AlSiMag blend) with the slots for the resistor wires in the middle. Inside this is only the stainless tube - blackened by the refractory sealant they put over that whole end in that vintage of HotCat (the ends are different on the new design of the "Independent Test". Then there is the outer tube about 4-5mm thick which we are told is SiN (plausible). I don't think there is anything between the alumina resistor assembly and the stainless tube.

I asked about this while correcting typos in the paper. One of the authors told me it was "corundum, corindone in Italian." Thanks - it is a bit of a surprise. It is true that the fluted cylinder with the slots - which holds the resistance wire could easily be corundum which is light-colored. Carborundum is blacker than black. This picture on Alan's site shows the proper coloration of corundum http://lenr.qumbu.com/web_hotcat_pics/130531_penon_07A.png But this picture, below it - shows a black cylinder inside the HotCat where another separate cylinder should be, and it is not light colored and not stainless. http://lenr.qumbu.com/web_hotcat_pics/130531_penon_08A.png Therefore I am still of the opinion - but without any real evidence other than this picture, that the ceramic which holds the stainless steel capsule is carborundum or SiC.
